<ul type="square">

<li><u>A point must use parentheses and commas:</u>
<blockquote>
<tt>(4.5, 3/7)</tt> &nbsp; is a valid point in 2 dimensions<br />
<tt>(pi,e,2)</tt> &nbsp; is a valid point in 3 dimensions 
</blockquote>
</li>

<li><u>If the answer is more than one point:</u>
<blockquote>
Enter your answer as a comma-separated list of points, for example: &nbsp;&nbsp;
<tt>(4,3), (5,10)</tt> 
</blockquote>
</li>

<li><u>If there are no solutions:</u>
<blockquote>
Enter &nbsp; <tt>NONE</tt> &nbsp; or &nbsp; <tt>DNE</tt> &nbsp; (this may vary from problem to problem)
</blockquote>
</li>

<li><u>Examples of constants used in points:</u>
<blockquote><tt>pi</tt>, <tt>e = e^1</tt></blockquote>
</li>

<li><u>Functions may be used in each coordinate of a point, but may not be applied across the parentheses or commas:</u>
<blockquote>
<tt>(sqrt(2),sqrt(5))</tt> &nbsp; is valid, but &nbsp; <tt>(sqrt(2,5))</tt> &nbsp; is not
